DETAILED DESCRIPTION

One or more example embodiments will be described in detail with reference to the accompanying drawings. Example embodiments, however, may be embodied in various different forms, and should not be construed as being limited to only the illustrated example embodiments. Rather, the illustrated example embodiments are provided as examples so that this disclosure will be thorough and complete, and will fully convey the concepts of this disclosure to those skilled in the art. Accordingly, known processes, elements, and techniques, may not be described with respect to some example embodiments. Unless otherwise noted, like reference characters denote like elements throughout the attached drawings and written description, and thus descriptions will not be repeated.

Although the terms “first,” “second,” “third,” etc., may be used herein to describe various elements, components, regions, layers, and/or sections, these elements, components, regions, layers, and/or sections, should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer, or section, from another region, layer, or section. Thus, a first element, component, region, layer, or section, discussed below may be termed a second element, component, region, layer, or section, without departing from the scope of this disclosure.

Spatially relative terms, such as “beneath,” “below,” “lower,” “under,” “above,” “upper,” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below,” “beneath,” or “under,” other elements or features would then be oriented “above” the other elements or features. Thus, the example terms “below” and “under” may encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly. In addition, when an element is referred to as being “between” two elements, the element may be the only element between the two elements, or one or more other intervening elements may be present.

As used herein, the singular forms “a,” “an,” and “the,” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “includes”, “including”, “included”, “include”, “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups, thereof. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. Expressions such as “at least one of,” when preceding a list of elements, modify the entire list of elements and do not modify the individual elements of the list. Also, the term “exemplary” is intended to refer to an example or illustration.

When an element is referred to as being “on,” “connected to,” “coupled to,” or “adjacent to,” another element, the element may be directly on, connected to, coupled to, or adjacent to, the other element, or one or more other intervening elements may be present. In contrast, when an element is referred to as being “directly on,” “directly connected to,” “directly coupled to,” or “immediately adjacent to,” another element there are no intervening elements present.

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which example embodiments belong. Terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and/or this disclosure, and should not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

Example embodiments may be described with reference to acts and symbolic representations of operations (e.g., in the form of flow charts, flow diagrams, data flow diagrams, structure diagrams, block diagrams, etc.) that may be implemented in conjunction with units and/or devices discussed in more detail below. Although discussed in a particularly manner, a function or operation specified in a specific block may be performed differently from the flow specified in a flowchart, flow diagram, etc. For example, functions or operations illustrated as being performed serially in two consecutive blocks may actually be performed simultaneously, or in some cases be performed in reverse order.

FIG. 3 is a block diagram illustrating constituent elements includable in a processor of a server according to example embodiments, and FIG. 4 is a flowchart illustrating methods performed at a server for dividing and sharing content according to example embodiments.

Referring to FIG. 3, the processor 222 of the server 150 may include a content manager 310, a content divider 320, a content distributor 330, an information manager 340, and a content sharer 350. The processor 222 and the constituent elements of the processor 222 may control the server 150 to perform operations S410 through S450 included in the methods of FIG. 4. Here, the processor 222 and the constituent elements of the processor 222 may be configured to execute instructions according to a code of at least one program and a code of an OS included in the memory 221. Also, the constituent elements of the processor 222 may be representations of different functions performed at the processor 222 in response to a control instruction provided from the OS or the application. In example embodiments, the content manager 310 may be used as a functional representation of the processor 222 that controls the server 150 to register and maintain digital content in response to the control instruction.

In operation S410, the content manager 310 may register and maintain digital content. A seller may register digital content the seller desires to sell to a platform associated with the server 150. In response thereto, the content manager 310 may store and manage the digital content registered by the seller in a database (not shown). Here, the database may serve to store and maintain the digital content under control of the content manager 310. Also, the database may be included as a constituent element constructed in the server 150. Alternatively, the entire database or a portion of the database may be present as an external database constructed on a separate system. Here, the term “digital content” refers to any type of information, materials, etc., represented in an electronic format to be distributed over the network 170. In example embodiments, the digital contents may include software (e.g., a mobile application, etc.), sound (e.g., music, sound effect, etc.), a moving picture (e.g., movie, a drama, an animation, a lecture, etc.), an image (e.g., comics, an illustration, a sticker, emoticon, etc.), a text (e.g., e-book, an article, etc.), and other contents (e.g., a game, an in-game item, etc.)

In operation S420, the content divider 320 may divide the digital content into a plurality of fragments as a division unit of the digital content. The division unit refers to a unit for dividing the digital content or a license of the digital content into a plurality of pieces. A variety of methods may be used as methods of dividing the digital content. A form of the division unit may be determined based on a type of digital content and the like. The content divider 320 may divide actual data (e.g., a file) of the digital content into N fragments. When the digital content includes data corresponding to the N fragments, the digital content may be available. The content divider 320 may divide a license of the digital content into N licenses. Here, when all of the N licenses are present, the N licenses may become a single license to use the digital content. The content divider 320 may divide the digital content into N layers. In example embodiments, when the digital content is a voice, an image, or a video, the content divider 320 may divide data into N layers. The content divider 320 may divide the digital content based on a time slot unit. In example embodiments, when the digital content is time-series data, such as a voice and a moving picture, the content divider 320 may divide the corresponding data into N time slots. The content divider 320 may divide the digital content based on a spatial-range unit. In example embodiments, when the digital content is spatial-array data, the digital content 320 may divide the corresponding data into N spatial ranges. The content divider 320 may divide the digital content into N libraries. In example embodiments, when the digital content is software, the content divider 320 may divide the digital content based on a single library unit. When all of the required libraries are present, a function of corresponding software may be executed. During the aforementioned digital content dividing process, a number of division units may be determined in advance. Alternatively, a number of division units may be determined based on digital content to be divided. In example embodiments, the content divider 320 may receive information about a number of users to share the digital content and may divide the corresponding digital content into a number of division units corresponding to the number of users to share the digital content.

In operation S430, the content distributor 330 may distribute the digital content based on a divided fragment unit. In example embodiments, in response to a purchase request for the digital content from the user, the content distributor 330 may sell the corresponding content based on a fragment unit that is divided based on a division unit. Here, the term “purchase” may inclusively indicate a paid or free transfer, a right transfer, and the like. The content distributor 330 may provide at least one of a plurality of fragments in a format capable of being owned by the user in response to a purchase request from the user. The content distributor 330 may transmit a portion of actual data of the digital content to the electronic device 110 based on a division unit applied to the digital content or may grant the user with a portion of a license of the digital content.

In operation 440, the information manager 340 may register and maintain all of the information required to provide a service associated with the digital content. Here, the information manager 340 may manage information about digital content owned by each user using the service. Here, the information about the digital content owned by each user may include a list of fragments divided from digital content purchased by each user. The information manager 340 may manage information about the digital content and information about a social relationship on an SNS for each user. The social relationship may be defined using a variety of methods. In example embodiments, an SNS buddy list may be defined as the social relationship. In example embodiments, a list of members included in an SNS chatroom or community may be defined as the social relationship. The information manager 340 may provide information about digital content owned by another user having a social relationship with a user that desires to purchase the digital content during a digital content distribution process to the user. In example embodiments, the information manager 340 may provide a list of fragments divided from digital content owned by each of other users with respect to each of the other users having the social relationship with the user. In example embodiments, the information manager 340 may provide information about a list of other users owning at least a portion of fragments of digital content that the user desires to purchase, or a portion of fragments that another user does not own among the fragments divided from the digital content that the user desires to purchase. Accordingly, the user may purchase a portion of the fragments of the digital content that the user desires to use through direct communication with another user having the social relationship with the user or based on information about the digital content owned by the other user having social relationship with the user.

In operation S450, the content sharer 350 may share the digital content divided into the plurality of fragments between the users having the social relationship, based on information about the digital content owned by each user and social relationship information. The other user having the social relationship with the user may use a fragment of the digital content owned by the user. On the contrary, the user may use a fragment of the digital content owned by the other user having the social relationship with the user. The content sharer 350 enables content fragments to be shared between the user and the other user having the social relationship with the user, and may provide corresponding content to the user when all of the fragments constituting the digital content are secured based on content fragments owned by the user and content fragments owned by the other user. The server 150 may set a sharing condition for each fragment of the digital content owned by the user if desired for the service. The sharing condition may be automatically set by a system or may be set as a condition requested by the user that owns a corresponding content fragment. In example embodiments, a number of other users allowed to share may be limited to be M, sharing counts may be limited, or a sharing period may be limited to be a certain period, such as 1 day for each fragment of the digital content owned by the user.

FIG. 5 is a flowchart illustrating methods of sharing digital content based on a social relationship according to example embodiments. Operations S501 through S504 of FIG. 5 may be performed at the content sharer 350, and may be included in operation S450 of FIG. 4 and thereby performed.

FIG. 5 illustrates a process of deriving a list of digital contents available to a user A.

In operation S501, the content sharer 350 may load a direct owning content fragment list of the user A. The direct owning content fragment list indicates a set of content fragments directly purchased and owned by the user A.

In operation S502, the content sharer 350 may derive an indirect owning content fragment list of the user A. The indirect owning content fragment list indicates a sum set of content fragments purchased and owned by other users having a social relationship with the user A.

In operation S503, the content sharer 350 may derive a final owning content fragment list of the user A based on the direct owning content fragment list and the indirect owning content fragment list of the user A. The final owning content fragment list indicates a sum set of the direct owning content fragment list and the indirect owning content fragment list.

In operation S504, the content sharer 350 may derive a content list available to the user A based on the final owning content fragment list of the user A. The content sharer 350 may provide corresponding digital content to the user A in an available state when all of the fragments that constitute the digital content are in a final owning state according to direct owning and indirect owning. That is, when all of the fragments of the digital content between the user A and the other users having the social relationship with the user A are secured, the corresponding content may be shared between the user A and the other users. In example embodiments, when at least one of the fragments that constitute the digital content is directly owned by the user A, the content sharer 350 may allow the user A to use the corresponding digital content. That is, although all of the fragments of the digital content are secured based on the social relationship of the user A, the user A may not directly own any of the fragments. In this case, the use of the digital content may be limited against the user A.

Information about digital content owned by each user and social relationship information may vary in real time and a content list available to the user may also be flexibly configured accordingly.

The server 150 may perform the process, such as operations S501 through S504, of FIG. 5 (1) at determined time intervals, (2) every time an event triggering a change of a list occurs, (3) at a point in time at which the user A requests information of the user A, or (4) at a point in time at which the user A requests sharing of digital content with at least one another user.

Here, the determined time interval may use various time intervals, such as every second, minute, day, etc. The event triggering the change of the list may indicate that a direct owning content fragment list is updated in response to a purchase action of the user, or that an indirect owning content fragment list of a user or another user having a social relationship with the user is updated due to a change in the social relationship between the users. Also, the point in time at which the user requests information of the user may indicate a case in which the user requests the server 150 for a current status of fragments owned by the user and information about an available content list using the electronic device 110. In response thereto, the server 150 may perform the process of FIG. 5 and may transmit the information requested by the user to the electronic device 110.

FIG. 6 illustrates a process of deriving an indirect owning content fragment list of the user A according to example embodiments. Operations S61 through S63 of FIG. 6 may be performed at the content sharer 350, and may be included in operation S502 of FIG. 5 and thereby performed.

In operation S61, the content sharer 350 may load a list F of other users having a social relationship with the user A. In example embodiments, the content sharer 350 may load a buddy list of buddies having a buddy relationship with the user A on an SNS. In example embodiments, the content sharer 350 may load a list of users included in a corresponding chatroom or community with respect to the SNS chatroom or community designated by the user A.

In operation S62, the content sharer 350 may load a content fragment list directly owned by each of the other users included in the list F of other users loaded in operation S61. In example embodiments, the content sharer 350 may load a separate content fragment list for each of the other users included in the list F. The content fragment list may include fragments directly purchased or otherwise owned by the respective other user.

In operation S63, the content sharer 350 may merge direct owning content fragment lists of all of the other users included in the list F of other users loaded in operation S61. Among fragments that constitute each piece of digital content, fragments owned by more than one other user may be regarded as a single fragment and merged.

Accordingly, the content sharer 350 may derive the indirect owning content fragment list of the user A by gathering content fragments directly owned by the other users having the social relationship with the user A.

FIG. 7 is a flowchart illustrating a process of deriving an available content list of the user A according to example embodiments. Operations S71 through S74 may be performed at the content sharer 350 and may be included in operation S504 and thereby performed.

In operation S71, the content sharer 350 may derive a content list CA that includes pieces of digital content of which at least one fragment is directly owned by the user A.

In operation S72, the content sharer 350 may derive a fragment list for each piece of digital content included in the content list CA, where the fragment list constitutes all of the fragments corresponding to the respective piece of digital content.

In operation S73, the content sharer 350 may verify whether an entire fragment list that constitutes the corresponding content is present in a final owning content fragment list of the user A, with respect to each piece of the digital contents included in the content list CA.

In operation S74, the content sharer 350 may derive, as available content of the user A, pieces of digital content for which the entirety of the corresponding fragment list is included in the final owning content fragment list of the user A among digital contents included in the content list CA. If at least one fragment in the fragment list of the content is absent in the final owning content fragment list of the user A, the corresponding content may be classified as content unavailable to the user A.

Accordingly, when at least one fragment in the fragment list of the digital content is present in the direct owning content fragment list of the user A and at the same time, any other remaining fragment(s) is present in the direct owning content fragment list of another user having a social relationship with the user A, the content sharer 350 may provide the corresponding content as content available to the user A.

FIG. 8 illustrates a data structure including a content fragment list owned by each user according to example embodiments.

Here, it is assumed that three users, user A, user B, and user C, are present, the user A has a social relationship with the user B and the user C, and a social relationship is not established between the user B and the user C.

Further, it is assumed that three pieces of content, content 1, content 2, and content 3, are present and each piece of content is divided based on a division unit and includes three fragments.

Each fragment of content includes information indicating direct owning, indirect owning, and final owning of each user. The direct owning indicates a content fragment directly purchased by a user, the indirect owning indicates a sum set of fragments directly owned by other users having a social relationship with the user, and the final owning indicates a sum set of the direct owning and the indirect owning.

When all of the fragments (e.g., three fragments) that constitute content are derived in a final owning state, the user may use the corresponding content. Here, the user may be required to own at least one fragment of the corresponding content to use the content.

Referring to FIG. 8, with respect to the contents 1, 2, and 3, the user A may satisfy a final owning condition since all of the fragments constituting the contents 1, 2, and 3 correspond to a sum of direct owning and indirect owning of the user A. Here, since fragments directly owned by the user A are present in the contents 1 and 2, the user A may be allowed to use the corresponding contents 1 and 2. Since a fragment directly owned by the user A is absent in the content 3, the user A may be disallowed to use the content 3.

The user B may satisfy a condition to directly own at least one fragment and a final owning condition according to direct owning and indirect owning of the user B and thus, may be allowed to use the content 2. In the case of the contents 1 and 3, a fragment that does not satisfy the final owning condition according to the direct owning and the indirect owning of the user B is present and thus, the user B may be disallowed to use the contents 1 and 3.

The user C directly owns all of the fragments that constitute the content 3 and satisfies a final owning condition without indirect owning and thus, may be allowed to use the content 3. In the case of the contents 1 and 2, a fragment that does not satisfy the final owning condition according to the direct owning and the indirect owning of the user C is present and thus, the user C may be disallowed to use the contents 1 and 2.

Accordingly, the content sharer 350 enables users having a social relationship to share content fragments owned by the users. Through this, when all of the fragments that constitute corresponding digital content are secured based on a direct owning fragment list and an indirect owning fragment list of the user, the content sharer 350 may provide the corresponding content to the user.

The aforementioned digital content providing methods may include a reduced number of operations or additional operations based on the detailed description of FIGS. 1 through 8. Also, at least two operations may be combined. Also, the order or locations of the operations may be changed.

According to example embodiments, it is possible to divide digital content into a plurality of fragments and to distribute the digital content divided into the plurality of fragments. Further, users having a social relationship may share digital content of a division unit. According to example embodiments, it is possible to effectively distribute network resources used for a service by distributing digital content based on a division unit. Through the distribution of the digital content based on the division unit, a user may use the digital content at a reduced price and a seller may improve sales of the digital content. According to example embodiments, users having a social relationship may share digital content therebetween by dividing the digital content based on a division unit. Since the users may be required to maintain the social relationship in order to share the digital content, it is possible to reduce service termination by users.
